2 Claims.

The present invention relates generally to apparatus adapted for use in the manufacture of composite or multi-fiavored frozen confectionery products, and it has particular relation to apparatus for partially filling the individual cavities of a multi-cavity mold with a given quantity of fluid material to be frozen.

Heretofore, the manufacture of composite or' multi-flavored frozen confectionery products, which consist of two or more separately flavored substances, or of two or more layers of the same substance but of different flavors and of contrasting colors, presented a problem of great dimculty in the partial filling of a multi-cavity mold structure, having a plurality of spaced dependent individual mold cavities, with uniform measured quantities of material in a cheap, efficient and sanitary manner. In the past it has either been necessary to carry out this step in the process by manually filling the individual cavities ofthe mold structure with separately measured quantitles of material, or to utilize a large and expensive filling machine of a complicated construction. In the former practice of manual filling, the operation was highly inefficient, expensive and time consuming; and in the latter case where the automatic filling machine was employed the initial installment cost was prohibitive for a majority of the manufacturers, and the upkeep, repair and investment was not warranted for the production of the average plant, and particularly is this true when consideration is given to the fact that the finished product has an extremely low sales price.

One object of the present invention is to provide a simple and eflicient portable displacing and proportioning device of an inexpensive construction, which is not only highly durable, but easy to clean, light in weight and entirely free of moving parts.

Another object of the invention is the provision of a simple and inexpensive portable device adapted to be suspended over a conventional multi-cavity mold structure for simultaneously allocating and uniformly partially filling the individual cavities thereof from a predetermined quantity of fluid material which is merely poured into said mold structure.

A further object of the invention is to provide a simple and efficient portable displacing and proportioning device, having removable displacer units which can be quickly and easily changed to vary the amount of fluid material desired to be allocated to each individual mold cavity.

Other and further objects and advantages of the invention reside in the detailed construction of the apparatus, which result in simplicity, economy and eificiency, and which will be apparent from the following description, wherein preferred forms of embodiment of the invention are shown, 5 reference being had to the accompanying drawings, forming a part hereof, in which:

Referring now to Figs. 1 to 7 of the drawings,

there is shown in Fig. 1 a portable displacing and proportioning device iii, 'consistingof a pair of spaced angle iron longitudinal supporting members l2 suitably secured adjacent each end. therer of by transversely extending U-shaped end frames i i, having upwardly extending arms l6 provided with handle gripping members 1.8 mounted transversely adjacent the upper ends thereof. Stops 28 are suitably mounted by screws 2! intermediate the ends of the upwardly extending arms i 6 of the U-shaped frames l8, providing means for suspending the portable carrier device I 8 over a conventional multi-cavity mold.

Transversely extending flat supporting members 22 are mounted between the angle iron frame members i2, and are secured thereto by spotwelding or other suitable fastening means. The members 22 are uniformly spaced longitudinally of the frame supporting structure of the device ill. Hollow displacer units, 24, made of non-corrosive, stainless, metal,-are removably mounted to the underside of the supporting members: 22 by machine screws 28. The units 24 are smaller in cross-sectional dimensions than the mold cavities with which they are intended to be used, and are of a greater length than the depth of said cavities for reasons hereinafter more fully explained.

Means in the form of upwardly extending and tapering indentations 28 are positioned adjacent the lower ends of the displacer units 28.

Referring now to Figs. 4, 5 and 6, there is shown the manner in which the device it] is adapted to be used in conjunction with a multi-cavity mold of conventional construction. The mold structure 30 consists of a mold pan 32, having upstanding sidewalls 34 and end walls 38, and a plurality of integrally formed individual open-top mold cavities 38 depending therefrom, which are provided adjacent the lower closed bottoms'thereof with a plurality of inwardly projecting perimetri-' cally spaced and upwardly tapering ribs 48. The specific features of thisconventional form of mold comprises no part of the invention covered by this application.

The portable displacing and proportioning device ID is suspended over the mold structure 38, the stops 20 of the device l8 resting upon the upper edges of the sidewalls 34 thereof, and supporting the majority of the weight of the device iii. In this position the displacer units 24, being correspondingly spaced on the frame structure of the device ID to the spacing arrangement of the individual cavities of the mold structure 30, extend downwardly with one spacer unit 24 extending into each mold cavity 38, the indentations 48 on the lower portion of said displacer units 24 engage the correspondingly shaped projecting ribs 30 of the mold cavity 38, thereby accurately positioning and centering the displacer unit 48 axially in spaced relation to the inner surfaces of the mold cavity 38. .It ivill be noted that the upper parts of the displacer units 24 extend above the tops of the individual mold cavities 38 and the mold pan 32.

With the portable displacing and proportioning device i8 superimposed over the mold structure 38, as above described, a predetermined amount of fluid material 42, equal in volume to the combined cubical dimensions of the spaces between thedisplacerunits and. the inner surfaces of the mold cavities 38, may'be'pouredinto the mold pan 32 of the mold structure 38. The displacer units 26 will prevent more than the desired amount of. liquid material 42 to flow into each of'fiuid material. The fact that the displacer units '23 extend above the tops of the mold cavities 38 and the mold pan 32 prevents more than the desired amount to flow into any. one mold cavity at any time, thereby causing any excess material to be diverted 'into any unfilled mold cavities.

Upon removal of the portable displacing and proportioning device ID, with its depending displacer units 28, from the mold structure 30, the fluid material 82 in each mold cavity 38 will gravitate to the bottom of said cavities, as best shown in Fig. 5.

A preformed confectionery core 44,- which has been suitably bonded to a handle member it in any suitable manner, is shown secured in spaced depending relation in a portable carrier 58. These cores id may be inserted into the mold structure 38, with the individual cores extending into the fluid material 42 in each mold, thereby displacing a portion of the material 32 and causing it to rise up in the mold cavity 38 around the remainder of the core to completely enrobe the same, as best shown in Fig. 6. The mold structure 30 and contents are now ready to be positioned in a brinetank 58, containing circulating refrigerating brine 52, and allowed to remain therein until the fluid material 42 is completely frozen and bonded to the frozen core 34. Thereupon, the mold structure 38 is removed from the brine 52, and the finished frozen confectionery products 58, which are shown in Fig. 7, may be removed from their respective mold cavities 38 in any suitable manner. No claim is made herein to the novel form of the finished product shown in Fig. 7 hereof, which has been used solely for illustrative purposes, it being understood that the subject-matter thereof forms the basis of a copending design application filed by the inventor Norman M. Thomas on even date herewith, and given Serial No. D-69,123, now Letters Patent Design No. 105,151, issued June 29, 1937.

Referring now to Figs. 8 to 13 of the drawings, there is shown a modified form of conventional multi-cavity mold 6!, consisting of a mold pan 63, having upstanding sidewalls and end walls 61, and a plurality of integrally formed individual open-top mold cavities 69 depending therefrom.

The portable displacing and proportioning device H, shown in Figs. 9 and 10, is constructed identically to the device l0 except that instead of the depending displacer units 26 a modified substituted hollow metal displacer units 73 are provided with a plurality of longitudinally extending ribs I5, which are spaced perimetrically thereof, and a transversely extending bottom ribll.

The modified form of displacer unit 19, shown 7 in Figs. 11 and 12, may be substituted for the displacer units 13 in the displacing and proportioning device H. the means for engaging the inner surfaces of the mold cavities. are shown in the form of semi-spherical protuberances 8|, a plurality of which are mounted in spaced relation on each of the scope of the appended claims.

the faces of thedisplacer unit 19.

The form of completed composite frozen conhave been broken away to show the relative position of the different substances.

Although I have only describedin detail several forms which myinvention may assume, it will be readily apparent tothose skilled in the art that the invention is not so limited, but that various other modifications may be made therein without departing from the spirit thereof or from What I claim is:

1. Iri-apparatusfor molding a plurality of composite frozen confections simultaneously wherein amultl-cavity mold having a plurality of spaced cavities, which are to be partially filled with a liquid syrup to be frozen are each provided with spaced inwardly projecting upwardly tapered longitudinal ribs, the combination with said mold In this form of displacer'unit,
